2013 GMC SIERRA 2500HD AND 3500HD TRUCKS WORK HARD WITH STYLE

GMC Sierra 2500HD and 3500HD trucks work hard – and do it with unmistakable GMC style. There are 10 Sierra 2500HD models, eight 3500HD models and six Sierra Denali HD models – including regular cab, extended cab and crew cab body styles offered in 2WD and 4WD, as well as single- and dual-rear-wheel configurations. All are available with either a standard gas V-8 or the powerful Duramax 6.6L turbo-diesel.

Their capabilities include:

2500HD maximum payload of 4,212 pounds (1,910 kg) with the available Performance Package on regular cab long box models (2WD)

Work Truck, SLE and SLT models are offered, as well as the distinctive Sierra Denali HD models, which blend heavy-duty capability with distinctive style and luxury appointments. Range highlights include:

The Duramax powertrain is proven combination, with more than 1.2 million sold since 2000.

New for 2013 is a bi-fuel compressed natural gas fuel system and bi-fuel-compatible version of the 6.0L V-8 engine. It features hardened valves and valves seats that enable to run on gasoline or compressed natural gas. The bi-fuel package is available on 2500HD extended cab models.

The 6.0L powertrain now features powertrain grade braking in the normal transmission mode – it was previously incorporated only when the Tow/Haul mode was activated. It uses engine torque to help slow the vehicle on descents, which helps reduce brake wear.

Sierra 2500HD and 3500HD trucks are comfortable and connected, with technology features including GMC WiFi (dealer-installed), USB connectivity, Bluetooth phone connectivity, SiriusXM Satellite Radio, OnStar 9.0 and navigation. There’s also a navigation radio with CD, USB port and an 80-gig hard drive (30 gigs of memory), along with heated and cooled front seats available on SLT and standard on Denali models.

Also new for 2013 is a pair of exterior colors – Sonoma Red Metallic and Heritage Blue Metallic (not available on Denali).

A Vortec 6.0L gas V-8 with variable valve timing is matched with the Hydra-Matic 6L90 six-speed automatic transmission as the standard powertrain across the Sierra HD model range. This combination delivers excellent performance and efficiency, with an emphasis on low-rpm performance. It is rated at 360 horsepower (268 kW) and 380 lb.-ft. of torque (515 Nm).

New for 2013 is a bi-fuel version of the 6.0L engine – known by its LC8 engine code – which features special hardened valves and valve seats that enables it to run on compressed natural gas (CNG) or gasoline.

The Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 2500HD and 3500HD models. Highlights of the Duramax diesel include:

Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes

Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills

Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel

B20 biodiesel capability for an alternative fueling option.

The Allison 1000 features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads.

Sierra HD chassis and suspension

All Sierra HD models feature fully boxed frame assemblies – 18 different assemblies that accommodate all of the range’s configurations. The front sections are hydroformed.

Additional chassis and suspension features include:

Front gross axle weight rating up to 5,600 pounds (2,540 kg), enabling a snow plow to be used on all 4WD cab configurations with the available snow plow prep package.

Five different torsion bar rates support five different front gross axle weight ratings to help stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.

Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models.

The frame-mounted hitch for conventional trailering has a box-tube design and supports up to 18,000 pounds (8,164 kg).

Sierra HD safety and crash-avoidance features

Sierra has a strong body structure to absorb crash energy and provide a protective “safety cage” around occupants. Head curtain side air bags with rollover protection and seat-mounted side-impact air bags for driver and right-front passenger are standard on Denali models with single rear wheels and available on other Sierra HD models. The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment, while the seat-mounted air bags provide thorax and pelvic protection.

Additional safety features include:

StabiliTrak electronic stability control system is standard on all single-rear-wheel models

Large, four-wheel disc brakes with four-wheel ABS are standard on all models

Rear vision camera system is standard on Denali and available on other models

Trailer sway control system on all single-rear-wheel models

Hill start assist is standard on single-rear-wheel models.

Trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system will use electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck and requires no input from the driver.

The hill start assist system is automatically engaged when sensors detect the vehicle is on grade of approximately 5 percent or greater. It holds the brakes for 1.5 seconds or until the gas pedal is pressed, preventing rollback – it is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.

OnStar details

OnStar is standard on all Sierra 2500HD and 3500HD models, except Work Truck, where it is available. It uses GPS and cellular phone technology to automatically call for help in the event of crash. OnStar subscribers also can use the service to be Good Samaritans by sending help to other motorists, and to call for help in other non-crash emergencies. Additional features:

Six months of complimentary OnStar Directions and Connections service with Turn-by-Turn Navigation for easier route guidance. The feature is easy to use because all directions are sent to the vehicle by an advisor, without the need to stop. Turn-by-Turn can be cost-effective, since map updates and aftermarket navigation systems are not needed

The MyGMC Owner App and OnStar RemoteLink™ App enable customers to keep track of essential vehicle information, including fuel level, fuel range, current mileage and more, as well as remote access to the vehicle’s features, such as unlocking doors or remotely starting the vehicle, from the convenience of a smartphone

Stolen Vehicle Assistance helps police track the vehicle.
